REFRIGERATION SYSTEM

Refrigerant

Non−chlorine, ozone friendly, R−410A. Unit pre−charged with refrigerant. See Specification table.

Outdoor Coil Fan

Direct drive fan moves large air volumes uniformly through entire condenser coil for high refrigerant cooling capacity. Vertical air discharge minimizes operating sounds and eliminates damage to lawn and shrubs. Fan motor has sleeve bearings and is inherently protected. Motor totally enclosed for maximum protection from weather, dust and corrosion Fan guard constructed of corrosion−resistant PVC (polyvinyl chloride) coated steel. Fan service access accomplished by removal of fan guard.

Copper Tube/Enhanced Fin Coil

Lennox designed and fabricated coil. Ripple−edged aluminum fins. Copper tube construction. Lanced fins provide maximum exposure of fin surface to air stream resulting in excellent heat transfer. Fin collars grip tubing for maximum contact area. Inverted coil circuiting prevents ice buildup at coil base in low ambients. Discharge gas enters bottom of coil during defrost and heat of refrigerant flows counter to water drainage resulting in extremely clean and unobstructed fins and tubes. Fin spacing allows rapid and complete water drainage. Flared shoulder tubing connections/silver soldering construction. Coil is factory tested under high pressure to insure leakproof construction. Entire coil is accessible for cleaning.

Expansion Valve − Outdoor Unit

Designed and sized specifically for use in heat pump system. Sensing bulb is located on the line between reversing valve and the coil thus sensing suction temperature in any cycle. Factory installed and piped.

Discharge Temperature Switch

Shuts off unit if operating conditions cause the compressor discharge line temperature to rise above setpoint. Protects compressor from excessive pressure / temperature. Automatic reset when temperature drops below setpoint.

High Pressure Switch

Shuts off unit if abnormal operating conditions cause the discharge pressure to rise above setting. Protects compressor from excessive condensing pressure. Automatic reset.

Low Pressure Switch

Shuts off unit if suction pressure falls below setting. Provides loss of charge and freeze-up protection. Automatic reset.

Hi-Capacity Liquid Line Drier

Factory installed in the liquid line, the drier traps moisture or dirt that could contaminate the refrigerant system. 100% molecular−sieve bead type drier.

Reversing Valve

4-way interchange reversing valve effects a rapid change in direction of refrigerant flow resulting in quick changeover from cooling to heating and vice versa. Valve operates on pressure differential between outdoor unit and indoor unit of the system. Factory installed.

OPTIONS

Expansion Valve Kits

Must be ordered extra and field installed on certain indoor units. See ARI Ratings tables. Chatleff style fitting.

Freezestat

Installs on or near the discharge line of the evaporator or on the suction line. Senses suction line temperature and cycles the compressor off when suction line temperature falls below it’s setpoint. Opens at 29°F and closes at 58°F.

Refrigerant Line Sets

Refrigerant lines (suction & liquid) are shipped refrigeration clean. Lines are cleaned, dried, pressurized, and sealed at factory. Suction line fully insulated. L15 lines are stubbed at both ends. See Specifications table for selection. Not available for −060 model and must be field fabricated.

COMPRESSOR

Copeland Scroll Ultra Techt Two−Stage Compressor

Compressor features high efficiency with uniform suction flow, constant discharge flow and high volumetric efficiency and quiet operation. Compressor consists of two involute spiral scrolls matched together to generate a series of crescent shaped gas pockets between them. During compression, one scroll remains stationary while the other scroll orbits around it. Gas is drawn into the outer pocket, the pocket is sealed as the scroll rotates. As the spiral movement continues, gas pockets are pushed to the center of the scrolls. Volume between the pockets is simultaneously reduced. When pocket reaches the center, gas is now at high pressure and is forced out of a port located in the center

efficiency. Scroll compressor is tolerant to the effects of slugging and contaminants. If this occurs, scrolls separate, allowing liquid or contaminants to to be worked toward the center and discharged. On the fixed scroll there are two bypass ports in the first suction pocket. On the outside of the fixed scroll there is a slider ring" that is controlled by an internal solenoid that will rotate and cover the bypass ports. When the thermostat calls for first−stage cooling, the bypass ports are open and the compressor operates at 67% capacity, creating more cost−effective and efficient compressor operation. The bypassed refrigerant is returned to the compressor housing through the bypass ports. When the thermostat calls for second−stage cooling, the internal solenoid is energized, the slider ring rotates and covers the bypass ports, and the compressor operates at full capacity. Low gas pulses during compression reduces operational sound levels. Compressor motor is internally protected from excessive current and temperature. Compressor is installed in the unit on specially formulated, resilient rubber mounts for better sound dampening and vibration free operation.

FEATURES

COMPRESSOR (CONTINUED)

Crankcase Heater

Crankcase heater prevents migration of liquid refrigerant into compressor and ensures proper compressor lubrication.

Outdoor Thermostat Kit

An outdoor thermostat can be used to lock out some of the electric heating elements on indoor units where two−stage control is applicable. Outdoor thermostat maintains the heating load on the low power input as long as possible before allowing the full power load to come on the line. Thermostat kit and mounting box must be ordered extra.

Cabinet

ARI RATINGS − INDOOR COIL / AIR HANDLER SUBSTITUTION

Substituting Coils in the ARI Tables

Most R−22 and R−410A indoor coils and air handlers are the same except for the factory installed expansion device. C33 coils can be used in place of the CX34 coils, CB26UH−R, CB30M and CB31MV air handlers can be used in place of the CB26XUH, CBX32M and CBX32MV, respectively.

The expansion device is based on the size of the outdoor unit. The factory installed RFC or TXV on the C33/CB26UH−R/CB31MV/CB30M must be replaced to correspond to the outdoor unit. The correct TXV’s are:

3 ton heat pumps 49L24 4−5 ton heat pumps 91M02

Example:

A four−ton heat pump is being installed. The ARI table shows that CBX32MV−048 is a matching air handler. A CB31MV−51 with a 91M02 TXV can be used in its place.
